Replace Batteries; Check Monitor Functions And All Other Instrument Operation - Hitachi ZW 370-6 Operator's Manual

Replace Batteries

IMPORTANT: Before adjusting electrical system or
welding on the machine, disconnect the negative side
of the battery, or turn the battery disconnect switch to
OFF position.
Your machine has two 12-volt batteries with negative (-)
ground.
If one battery in a 24-volt system has failed but the other is
still good, replace the failed battery with an operable battery
of the same type. For example, replace a failed maintenance-
free battery with a new maintenance-free battery.
Different types of batteries may have different rates of charge.
This difference could overload one of the batteries and cause
it to fail.
Check Monitor Functions and All Other Instrument
Operation
--- every 10 hours (daily)
Run the engine at low idle when checking the instruments.
The monitor indicates alarm, caution and confirmation status
in red, orange, and normal operative condition in blue or
green respectively.
Check each gauge or meter if its needle is moved with the key
switch ON. The needle shall be moved to the blue range when
normal and to the red range when abnormal.
Refer to the Group of Operator's Station in Section 1 for more
information.
